Globally, over 50% of the population lives in urban areas today. By 2045, the world’s urban population will increase by 1.5 times to 6 billion. Public transport is a good way to reduce congestion, save environment and people from health-harming emissions in urban areas, especially when they run on alternative, cleaner fuels. The European Commission strongly encourages the use of public transport as part of the mix of modes which each person living or working in a city can use.
Public transport services are mobility systems (via land, sea, lagoon, river, etc.) with pre-established routes, timetables, frequencies and fares in a regional or even inter-regional territory. Means such as train, bus, metro play a strategic role in boosting the adoption of new mobility habits: it is possible to maximise resources and time by combining the different means available, contributing to the reduction of CO2 emissions and traffic, with all its problems.
In fact, a single person who switches from a 30-km commuting alone by car to existing public transportation, can reduce his/her annual CO2 emissions by around 9 kg per day, or more than 21 tons in a year. That is equal to 10% reduction in all greenhouse gases produced by a typical two-adult, two-car household.
